  1. 6. Aspects of Intraoperative Ablation for Atrial Fibrillation

    Författare :Birgitta Johansson; Göteborgs universitet; []
    Nyckelord :atrial fibrillation; intraoperative ablation; radiofrequency; cryo; epicardial; quality of life; atrial function; predictors of rhythm;

    Sammanfattning : Background: Increasing knowledge about mechanisms that trigger and maintain atrial fibrillation (AF) has influenced the possibilities for treatment and even cure of AF. The surgical Cox Maze III procedure is still the gold standard for the curative treatment of AF. LÄS MER

  3. 7. Outcomes and safety of new techniques for pulmonary vein isolation in patients with paroxysmal and persistent atrial fibrillation : A study based on randomised trials and registries

    Författare :David Mörtsell; Carina Blomström-Lundqvist; Stefan Lönnerholm; Isabel Deisenhofer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; antiarrhythmic drugs; ablation; cryoballoon; radiofrequency; pulmonary vein isolation; quality of life; arrhythmia monitoring; implantable cardiac monitor; atrial fibrillation burden; health economics; Cardiology; Kardiologi;

    Sammanfattning : Atrial fibrillation (AF) is a common disease with a high prevalence in the adult population. Treatment of AF encompasses antiarrhythmic drugs and catheter ablation to reduce symptoms. LÄS MER

  4. 8. Atrial fibrillation in cardiac surgery

    Författare :Anders Ahlsson; Anders Englund; Johan Brandt; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; Inflammation; CABG surgery; Survival analysis; Follow-up studies; Ablation; Microwave; Transmurality; Atrial function; Tissue velocity echocardiography; Thoracic surgery; Thoraxkirurgi; Kirurgi; särskilt thoraxkirurgi; Surgery esp. Thoracic and Cardivascular Surgery;

    Sammanfattning : Atrial fibrillation (AF) is the most common arrhythmia seen in clinical practice. In cardiac surgery, one-third of the patients experience episodes of AF during the first postoperative days (postoperative AF), and patients with preoperative AF (concomitant AF) can be offered ablation procedures in conjunction with surgery, in order to restore ordinary sinus rhythm (SR).

  5. 9. Adhesion to machined and laser ablated wood surfaces

    Författare :Micael Stehr; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; ablation; adhesion; checks; coating; cracks; excimer laser; gluing; IR laser; mechanical machining; mechanical weak boundary layer; microscopy; notched specimens; pine; planing; sample preparation; sawing; scanning electronmicroscopy; spruce; tip-cracks; UV laser; weak boundary layer; wood;

    Sammanfattning : This thesis is a contribution to the R&D-program ValueActivation at KTH,Division of Wood Technology and Processingand containsfive papers related to the evaluation and development ofmachining techniques (mechanical and irradiation treatments)whereby weak boundaries at the wood surfaces in the form of(mechanical) weak boundary layers and (micro) cracks due tomechanical treatment can be avoided.The first paper describes the development of a method–using a UV laser–to study the mechanically weakenedboundaries.
